Moving to a new Directory

Hello,

At present my bodybuilding community is becoming quite large, so i have thought of expanding it to a portal.
I have decided that i will use vBAdvanced CMPS, my only question is, what do i do in regards to moving the forums to another directory?

At the moment the forums exist on the main root of the server [public_html/], but in order for VBA CMPS to work effectively i need the forums moved to /forums or /forum

Would it just involve editing the config file? or a complete back-up and re-install?

Any help is greatly appreciated,
Nick

Edit: More details added

You dont need to move it. Name the forums' index.php to say forum.php. Then just edit the option in vbulletin options.
